Maca and her friends assault Sara at the local swimming pool and steal her backpack and clothes. As she trudges away in her bathing suit, a group of men harass her on the road. In a side road she spots a parked van that the kidnapper uses, and Claudia appears through the window begging Sara to save her, but Sara is frozen as the van drives off, leaving a towel behind.

She hurries home after the pool incident and decides not to tell anyone what happened. She keeps her fear hidden and tries to act normal in front of her family. The secret of the van and Claudia's plea lingers unsaid as life in the town continues.

News spreads that the pool lifeguard has been found dead and the waitress has vanished, along with the three missing girls. Sara is questioned by her mother and the Civil Guard about her whereabouts and whether she was at the pool. She denies having been there and guards her secret.

Sara steals her father's phone to trace the location of the missing girls and ventures into the forest. She locates her backpack and the phone, confirming she was there. The discovery marks a dangerous turn as she becomes entangled with the kidnapper's trail.

In the forest, the kidnapper warns Sara to be quiet and shows an unsettling, almost affectionate side toward her before slipping away. Sara remains fearful but manages to observe his movements. This encounter sharpens her awareness of the danger surrounding the missing girls.

Family members of the missing girls organize a search of the forest and nearby areas. Elena, Claudia's mother, and others push deeper into the woods until they discover the body of the missing waitress, confirming a grim pattern behind the disappearances. The mood in town grows darker and more suspicious.

Pedro, a friend of the missing girls, introduces Sara to marijuana and pushes her to reveal what she knows. He confirms that Sara had been at the pool and that she lied when denying it. The crowd in town grows uneasy as Pedro hints at his own knowledge of the events and the possibility that he is involved.

Elena lashes out at Sara, exposing the tension in the town and forcing Sara to admit a part of the truth. Pedro publicly exposes the hidden details to the crowd, prompting the Civil Guard to take Sara in for questioning. Sara starts to tell what she knows, but the onset of her period interrupts the interview.

Unbeknownst to Sara and Asun, the kidnapper arrives at their home and assaults Sara's father before abducting Sara to an abandoned warehouse. The town remains unaware of the immediate danger as Sara is taken away in silence.

Inside the abandoned warehouse, Sara discovers Roci and Claudia alive but gagged and suspended by their wrists. She also finds Maca's decomposing body, confirming the kidnapper's brutality. The kidnapper returns and tries to pressure Sara into killing the two girls.

Sara fights the kidnapper, ultimately killing him after a brutal struggle. He accidentally fires his shotgun, blowing off Claudia's hand in the chaos. Sara bites him during the struggle and constrains him until he dies.

Sara shoots the ropes suspending Roci and Claudia, freeing them from their bondage. She chooses not to kill the two girls despite the killer's insinuations, and then walks along a road where she meets Pedro on a motorbike and returns to town with him.
